Why I am a “skeptic”

[jmotivator]

LOL It is not like you homes thermostat, it controls the entire Earth

You still don't get it. Polar bears are marine animals and their habitat is the ice floating in the sea. Humans are not "encroaching" on that habitat they are destroying it by burning millions of tons of fossil fuel and warming the climate. That is what is driving them to the garbage dumps.

Sooo.. "marine animals" like whales?

Note how much of the Polar Bear habitat is not water:



If you manage to read the map properly you will see that...

1) Polar bear NORMAL range is ALL LAND
2) Polar Bear OCCAISIONAL range is on Sea Ice.

Here is another article that you would likely only read the headline, make no meaningful connections beyond what you are told to make, and miss the whole point:

Newly documented population of polar bears in Southeast Greenland sheds light on the species’ future in a warming Arctic

A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could...

www.washington.edu

The story attempts to connect itself to this manufactured plight of polar bears but the actual takeaway is:

1) Pretty hard to make definitive ruling that the population of the polar bears is shrinking when they are still finding polar bear populations... (see earlier argument about the trouble with using regional populations to determine population count)
2) This particular polar bear population is doing just fine living like every other population of arctic bears...

You really need to stop this nonsense....

It is difficult to argue with someone who cannot see the forest for the trees. The discovery is interesting but does not change the facts as the article you linked clearly states. The scientific name for polar bears is ursus maritimus and you do not need to know latin to know what that name refers to. It means marine bear.
“Polar bears are threatened by sea ice loss due to climate change. This new population gives us some insight into how the species might persist into the future,” said Laidre, who is also a UW associate professor of aquatic and fishery sciences. “But we need to be careful about extrapolating our findings, because the glacier ice that makes it possible for Southeast Greenland bears to survive is not available in most of the Arctic.”

LOL!! So I show you that the normal polar bear range is all land and your counter argument is that the name assigned to the Polar Bear in 1774 has "maritimus" in it so no, it's a marine mammal? Is that the argument you are going with?

Here are the facts: The Polar Bears normally live on land, and occasionally spend time on the sea ice. Insofar as the 1774 taxonomy can be used to describe the life of a polar bear, polar bears do live within a few hundred miles of the ocean most of the time and feed on many other mammals that are far more dependent on the oceans than a polar bear (seals, whales, walrus), and also other arctic animals like deer.

Polar bears follow the seal populations which, in the deep winter, move farther out on the sea ice because that is where the access to the water is. Polar bears will be where the food sources are. For seals that is on land if there is no ice. But that isn't the primary hunting ground for polar bears, who spend most of their time on land.

Your misconceptions are not facts. Seals do not come on land except to breed. Polar bears go out on the ice and wait at breathing holes for seals. That has always been their primary feeding method and where they got most of their calories to support their large size. They cannot compete with smaller grizzly's for the limited sources of food on land leading to their presence in garbage dumps.

Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe. When the seal nears the surface, the polar bear will bite or grab the seal and pull it onto land to feed. They also eat walruses and whale carcasses. Polar bears will search out bird eggs and other food sources, but none of these are abundant enough to sustain the large body mass and dense populations of polar bears.

Polar bears are in serious danger of going extinct due to climate change. In 2008, the polar bear became the first vertebrate species to be listed under the U.S. Endangered Species Act as threatened due to predicted climate change. The Secretary of Interior listed the polar bear as threatened but restricted the Endangered Species Act's protections, and thus the polar bear's future is still very much in jeopardy.

The chief threat to the polar bear is the loss of its sea ice habitat due to climate change. As suggested by its specific scientific name (Ursus maritimus), the polar bear is actually a marine mammal that spends far more time at sea than it does on land. It's on the Arctic ice that the polar bear makes its living, which is why climate change is such a serious threat to its well-being. Polar bears are being impacted by climate change in several ways.

Again, Polar bears spend most of their time on land, not on the sea ice. Your national wildlife fund source is making you ignorant.

Polar bears were named in 1774. A considerable amount of information on the Polar Bear habitat have been discovered in the intervening 249 years including that they don't live in the ocean....

LOL Then why do scientists today that study polar bears say this? Part of a large conspiracy to ruin your day?

LOL!! That Specific scientist was a scientist 249 years ago... should we go through the accuracy of scientific discoveries from 200+ years ago? 250 years ago they couldn't even agree that Africans were human.

Again, the name doesn't change the fact that the Polar Bear's primary habitat in land, not ocean.

I remember that Apple had a star map of the entire sky for one of their demos, and that there were quite a bit more stars in the
Northern Hemisphere. The reason is that people had been looking at the stars longer in the Northern Hemisphere.
A scientist 250 years ago in the Arctic, would likely have been on a ship, and seeing a bear out at sea, basically called him a sea bear.

So...

Once again, no proper response to what I said.

Do you seriously expect any chaotic system with multiple variables modulating it to stay even within 2%?

 

[ralfy]

It's pointless to be skeptical due to environmental damage and pollution, but it's also pointless to take action because the world economy needs more resources and energy than the planet can provide without leading to envirommental damage and pollution.

Polar bears are indeed land animals. Always giving birth on land. It is where the critter gives birth that matters, not its range.

Alaska has two polar bear populations: the Southern Beaufort Sea population and the Chukchi Sea population. The Southern Beaufort Sea population is in decline, while the Chukchi Sea population is increasing.

Polar Bear Species Profile, Alaska Department of Fish and Game

General information about Polar Bear in Alaska such as description, life history, range, habitat and more.

www.adfg.alaska.gov

Your range map is also a bit off. The Chukchi Sea population does not get any further south than around Nome. They do not reach the Aleutian Islands as your map depicts. The sea ice does not even reach that far south during the height of Winter. The furthest south that the sea freezes during the Winter is 61°N. Valdez, Alaska, is the furthest northern "warm water" port on the North American continent. So the sea ice never reaches the Aleutian Islands, which means that there are no polar bears in that area.

Pollution is one thing everyone can agree is bad and can effectively be tackled

However that has little to do with AGW skepticism given CO2 is not pollution (quite the contrary in fact).

Alarmists just love conflating the two sadly to the detriment of rational pragmatic discussion
